The most likely reason for frame replacement (for me anyway) has been broken tabs on which the landing gear struts mount. Has anyone come up with a trick to reinforce these tabs so they don't break as easy.

I was even considering putting saw cuts in the white plastic landing gear struts just so that they would break easier and save the frame. It is just so much work to transfer everything to a new frame.

I've been wondering about this as I don't fancy trying to replace a frame. I've seen racing cars where the rear wing (fender) is attached with nylon bolts rather than metal ones so that they break on impact rather than ripping the bodywork. I wonder if we could do the same with the B400's landing gear bolts? What size are they?

You would need to drill the skid struts for 2mm. but can you find 2mm nylon screws.
2/56 is a touch larger, but you might have better luck finding them in nylon.

But along this line of thought...how about mounting ball studs in the tabs, pointing down. Then drill a tight fitting hole in the landing skid. If you could get a "snap on" skid, that might be the answer. It just has to stay on in flight...maybe tie some monofiliment line to hold it together. Just a wacky thought....

I was lazy this morning, so I just drilled a couple of 3/32 holes in each strut. The hope is that the strut will break first. But I also ordered some 2mm zip ties. If the ties usually break first, it will save both the strut AND the tab.

I've installed the 2mm nylon bolts, nice easy mod just had to drill out the holes on the landing gear. Feels nice and secure but the bolts seem quite breakable. I doubt it will be long until we find out if they work!

Had my B400 for 2 Years have not replaced the main frame as of yet. Do have 500 skids on it. Do not know if it makes a diff, but I had the B400 skids on it untill last year and no broken tabs. You know I just jinxed myself with this post.
